Earlier Belarus President Alexander Lukashenko travelled to Russia to hold talks with Putin. The European Union and United States have imposed punitive measures on Belarus in recent months.
"Support for Belarus against the backdrop of such stifling sanctions is on the agenda, and the government has been given instructions and it is working in this regard," said Kremlin spokesman Dmitry Peskov.
Belarusian law enforcers conducted mass searches in offices of human rights organizations and activists. Specifically, the police searched the officer of lawyer Volodymyr Labkovich and deputy head of Vesna human rights centre Valentin Stefanovich.
DW cited Stefanovich's wife Alina who said that the search was conducted by workers of the Department of Financial Investigations of the Committee of Government Control. The search order contained provisions about organization of actions that breach civilian order, and tax evasion. Stefanovich had his computers and Belarusian opposition flags seized. The law enforcers took him in for 72 hours.
In Minsk, the police searched the apartment of Serhiy Sys, the Vesna activist. Then, they detained him as well. His fellow activists Yuriy Hubarevich and Katerina Sinyuk claimed that offices of local human rights organizations were searched, too.
